That's a pioneer head unit that I downloaded the trd background, all four speakers and 10"sub is powered by a alpine pdx-v9 best sounding stereo I ever heard!!!
I have A/T s on it 33's it only does it sometimes around corners, I put it in 4-lo last night with the down hill assistant and it was going off like crazy
The abs line? Mine truck only does it every so often, I was looking around and I guess there's something called yaw sensor or something just trying to see how people are fixing it
